how to make heating element for glue gun

To make the new heating element, the first thing you have to do is use a pair of pliers to remove the ceramic casing from the resistor, and carefully unwind the resistance wire. This is a very good thing for a resistor, but not for a heating element. No, seriously. This is fairly simple to do, as its mounting method shouldn't have changed from when the glue gun was new, and should just slot together. The stand will most likely have to be removed as well. It keeps the nozzle close to the place of glue used. 2 years ago, Answer Nicely done! The LED was glued in with hot glue. Since I wanted this glue gun to run off of 12 volts the resistance can then be changed to give the power required. By substituting the given values, this give us a required resistance of 10.2857 ohms. Best Budget, Mini: CC Better Mini Glue Gun. This is where I made the mistake, as the switch was installed right where one of the screw holes was! You will have to desolder the original wires from inside the cigarette lighter socket, and remove them and the strain relief from the actual connector. The closest wire-wound resistor I could find has a resistance of 10 ohms, giving (from the previous formula) a power consumption of 14.4 watts. These two inch long sections of wire had two little paddle contacts on the end and between them was a little rectangular chunk of aluminum. Add enough of them, like in the hand warming mouse or in a blow drier, and they will put out an ample amount of heat to increase the temperature of the glue gun to melt solder. A wide variety of heat glue gun options are available to you, such as application, temperature type, and glue stick length. Did you make this project? First, a rotary tool can be used to rough up the plastic and to neaten up the hole. 4 years ago, Yeah i also hate that, sometimes i use lighter, but i saw that some hot glue guns have "boost" function to make it heat faster. A momentary switch is what's wanted for this glue gun. After the thermal adhesive had dried, the resistance wire was then wrapped around the barrel. To do this you could purchase some nichrome wire, and measure out a length resulting in 10.2857 ohms. Expensive hair dryers, space heaters, and of course-mini glue guns from the dollar store. One of these is a thicker cable for the heating element, and the second is a length of thin (30 AWG) wire to power the LED. The 240 volt heating element has a positive thermal coefficient- as the temperature increases, so does the resistance. The diagram above shows a typical hot glue gun. This ensures the element cannot be left turned on, and reduces the risk of fire and other heat-related accidents. This was drilled parallel to the nozzle, meaning the LED points in the same direction as the nozzle, making the LED actually useful! You could use wood filler, epoxy, bog or a specially designed product, but I didn't have any of those to hand. It appeared to be brass or copper on the inside coated in what looked like steel though the wire was not magnetic. You need to know two things about the LED, its forward voltage and its forward current. The forums are retiring in 2021 and are now closed for new topics and comments. Congrats on your first instructable! The only components required are a white LED and a current limiting resistor of an appropriate value. The gun shape is useful in allowing the user to use a trigger action to force the stick through the heater, but not necessary for the actual application of glue… Key Features To remove it, simply cut down those lines. How this type of element works I do not understand. And why are you here? In the future I may end up rewiring the LED, so that it is on whenever the glue gun is connected to 12 volts, which should be much more useful. Glue guns should be switched on at least five to ten minutes before they are used. But wait, I hear you say, isn't that resistor only rated for 10 watts according to its own label?!! I measured the resistance, 2500 Ohms. You can now use your control circuit to adjust the output of a heating element and control its temperature. Why not build one? This was wrapped around the hot glue gun's barrel and held in place with thermal adhesive (I held it in place with some electrical tape until the adhesive had dried). Well, yes, but that rating is when the resistor has no additional cooling. The case was screwed together for this- ensuring the hole was centred and keeping a high quality look. To work out the required resistance, we can substitute ohm's law into the power equation, giving us r = (v^2)/P. I wouldn't think it could be. These are very hard to clean. Maybe ceramic? I guess I left out the orange cellophane wrapper in the picture. If the heating element is already reaching 120 C, at highest possibly, then there is a good chance you can get it up to the necessary heat … Once you do so, you can remove any retainer or other parts. Although not necessary, a light is a good thing to add, and the ease of doing this with a voltage as low as 12 makes it a no-brainer to install. Do you suppose it's ceramic. Try not to overflow the mold and/or have excess glue on the edges. Fix something while your camping? Check the heating element and temperature connections for loose wires or broken solder. I took it apart expecting to find a coil of … Firstly, the previously calculated resistor can be soldered directly to the LED's positive pin (the longer one, or the rounded side). Ever wanted a semi-portable hot glue gun? I saw a current draw of 1.323 amps at 12 volts, for a power consumption of 15.889 watts. Most hot glues melt at about 120 C. First thing I would check is the max temp. Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun.The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. The power consumption of something like this, with very low resistance, will change quite a lot with small changes in voltage- I measured 1.323 amps at 12 volts, but 1.52 amps at 13.8 volts! Help? MAKE SURE THE GLUE GUN IS UNPLUGGED! A hole was drilled in the plastic just below the nozzle. I wish mine would heat up that fast! My question is-where is the resistor here? To ensure we don't release the magic smoke, there are two things to consider: what voltage is being used and how much power you want converted to heat. This lowers the resistance, and the process repeats again and again. Voltage or Wattage Glue guns can often operate in 100 to 120 watts, which is enough to do your task. The parts list for a 12 volt hot glue gun is actually rather small. Firstly, we need to reinstall the trigger assembly. This is probably (read: definitely) not an ideal temperature for a hot glue gun. Somewhat approximately the 1900 ohms I was looking for. I have found that this is a very useful tool to have- it is more useful than it sounds. Hot glue is most commonly applied using a glue gun and comes in low . A wide variety of glue gun heating element options are available to you, There are 449 suppliers who sells glue gun heating element on Alibaba.com, mainly located in Asia. I have listed the components (and prices) from Jaycar electronics here in Australia (to support a local business) but I am sure you can find the same parts online if you can't find any at your local electronics store. Next, the LED is wired up. Almost done! Then, the cable (and strain relief) was glued into the base of the modified glue gun. I left the power connected for 3 minutes and the barrel heated up to over 250 degrees! Measuring the resistance of the whole glue gun, cold, at the prongs of the plug, the resistance is around 1900 Ohms. This allows the heating element and the glue next to it, to heat up. I am guessing that most glue guns are not going to get this hot. If you forget this you will forever be wondering (and cursing) why the new glue sticks keep falling out of the back of gun. Carefully add power to the heating element to let any residual glue melt. Add the stand and you're done! High temperature electrical insulation. This can then be smoother out so it follows the rest of the case exactly. After an initial warm up, I found that you could get about 4 minutes of gluing for every minute of holding the button down, which is very usable. The power of the heating element means it doesn't have to be held for long to get hot enough to glue stuff. PTC heating elements often have a negative temperature coefficient at low temperature. Found out it's a PTC element. How hot does the glue gun get? Therefore, a momentary switch MUST be used if you use a heating element of this style. I've got this little glue gun. After you get in, the trigger assembly has to be removed to access the heater barrel and the (no longer wanted) 240 volt AC heating element. Done! About: Hi all! 5 years ago. The added power sees the glue gun heating up even quicker, useful for something that operates portably. 4 years ago. The switch can then be installed. In this video we are showing how to make hot gun glue stick at home how to reuse your remain glue stick or used hot glue. Easy! Buy on Amazon. This makes it heat up really quickly and is very useful! if you leave a hot glue on overnight --- the glue gun stays on all nightANS 2 - All the glue will get really liquid and leak out and the heating element may burn out. I did not put any heatshrink over these connections, as the maximum temperature of heatshrink is normally 180 degrees Celsius, whereas in extreme circumstances the heating element could be double that. This insulates the barrel from the resistance wire. Also, as can be in the last image, the metal walls holding the 240 volt element in place were removed too. UniQual Low Temp Glue Gun has better ergonomics design for kids. Let me know in the comments if you used any of the ideas presented here in any of your own projects! You could, of course, use any colour you like, I just happened to have a 5mm high brightness cool white LED on hand. The same thing (two different wires) was done to the second pole of the switch, one for the LED and one thicker wire for the heating element. This is because hot glue in general is a useful adhesive- it is waterproof, relatively strong, can be removed (with effort) and is quick drying. It is a very easy (and inexpensive) task to make one yourself, and you get a pretty cool and useful tool to play around with too- so why wouldn't you want to build one! It is, however, possible to do this on an older glue gun, it is just simpler to do if the glue gun is clean. To make a glue gun, start by slicing the top and bottom off a soda can and cutting the tub open to form a flat sheet. The aim is to remove the strain relief from the red and black wires that the cigarette lighter plug comes with and install the strain relief on the sheathed cable that comes with the hot glue gun. Then, glue the strain relief halves around the conductors of the mains cable. 240 volts AC is only dangerous if you work on the glue gun whilst it is powered. The top countries of suppliers are China, Taiwan, China, and Vietnam, from which the percentage of glue gun heating element supply is 99%, 1%, and 1% respectively. 18 / 19. Then, tape the cone on top of a candle lighter so the tip just extends past the lighter. What am I missing thats creating 1900 Ohms of resistance? Keep in mind that the glue must dry before strength is significant and the project often. In this case, the resistor is attached to a large metal barrel, and additional cooling is supplied by the glue itself, as it has to heat up to melt! You can go through an entire stick of glue at once after heating it up, without touching the button, if you so wish! A hole must be drilled for the switch- in this case a 12mm one. I tried to cover the basics from choosing a glue gun to more advanced questions like can you use hot glue sticks for mold making. First of all how is it the same wattage at 120 and 240 volts? I found that the strain relief on the cigarette lighter plug looked easier to remove- so that's the one I worked on. Make sure the end of the strain relief is flush with the end of the cable sheath for a professional look. In this post, you will find 21 stunning crafts you can make with your hot glue gun and other useful tips and hacks for your glue gun projects. However, sometimes I need to get into a tight space or only use a little, thin strip or dab of glue. Answered. It's because I'm putting in more than twice the heating power (21 watts vs 10 watts) compared to how the glue gun was out of the box. Alibaba.com offers 976 heat glue gun products. This was secured at each end by wrapping it around itself a few times. On the package it said: 10 watts, AC 120-240V. Add a drop of hot glue to a coin and attach it to the problem area. It is a very useful thing to have that not many people actually think about! Price $32.25. Why not build one then? Instead I found that the power cord was soldered to two inch long twisty tie wire looking, insulated wires. All you need is a source of resistance and a flow of electrons though it. The heating process is regulated by thermistors, which allows the glue to be heated without the rest of the gun becoming hot and burning the user. This is perfect for field repairs of drones/ radio controlled planes, as well as general repairs or makings if you don't have access to mains power! Now, we did work out a power consumption of 14.4 watts. Hope you like and enjoy the stuff I make…, CheApR - Open Source Augmented Reality Smart Glasses, "High-Fivey" the Cardboard Micro:bit Robot. Industrial glue guns, on the other hand, offers a larger amount of melted glue released, can heat up faster and can be outfitted with larger glue sticks compared to mini glue guns. I took it apart expecting to find a coil of nichrome like in a soldering iron. Hot Glue Gun Uses: Fix Wobbly Furniture with a Penny. Let’s kick off this list with the Cobiz Glue Kit which offers a heating element that can … First of all how is it the same wattage at 120 and 240 volts? Next, cut a rectangle out of the sheet, twist it into a cone, and tape it closed. Removing the offending screw post (which was in the way of the switch) left a large and unsightly hole, which I wanted to fill in. In the end I decided on a power of 14 watts. It just means the button has to be held down to supply power to the heating element. then Sandwiching that were two more flattish rectangular pieces of aluminum. Finally, remove the metal clip that holds in the heating element. Just a few more things to do to make the finished product look neat. The LED I used has a forward voltage of 3.4 volts, and a forward current of 20mA, or 0.02 amps. To work out a value for the resistor, we can apply Kirchhoff's voltage law, which states that the sum of voltages around a circuit should equal zero. 244 ptc heating element for hot glue gun products are offered for sale by suppliers on Alibaba.com, of which electric heater parts accounts for 11%, heating equipment accounts for 1%. I would recommend you do the same (if you have any spare kapton tape). This is 4 watts more than the glue gun claims to use from 240 volts, but this isn't an issue, as it will merely decrease the time it takes for the glue gun to heat up. If you do end up with excess glue, use an … You can use it on a soldering iron, a hot glue gun, a candle warmer/coffee warmer, a heat lamp, or … This hot glue gun heats up from cold in about 45 seconds, and consumes 1.52 amps at the 13.8 volts of a car cigarette lighter socket, for a power of 21.08 watts. Finally, reassemble all the silicone parts back onto the heater barrel. Then the hole can be filled in form the inside of the case. Hot Glue Gun 50W Tilswall Mini Melt Gun. I'm seeing some wires hooked to a chunk of aluminum. Manufacturers commonly use a rubber casing on the nozzle to prevent burns. However, I did end up shortening the resistance wire a bit when it was wrapped around itself, giving a resistance of 9.03 ohms. Reply Here are some resistance vs temperature curves for TDK Series B59102 PTC heating elements, which are designed for use in home appliances such as hair curlers and glue guns:- . High-temperature glue guns heat to approximately 380°F and work well for projects that require stronger bonds. The wanted component is the cable strain relief, from either the cigarette lighter plug or from the 240 volt mains cable (that came with the original hot glue gun). That sounds like a piece of mica insulator. I dont know what type of wire that would be. Instead, I tried using hot glue to fill the hole. How glue gun heating element works? Low-temperature glue guns heat to approximately 250 °F, so they work best for materials that may be vulnerable to heat. Get your glue gun heated up and start filling the molds with glue! If you ever need to remove the glass, just heat the back with a heat gun to soften the glue. It must be that thin cellophane wrapper no? Its because you're a maker! See link here: http://dgbizhuo.en.alibaba.com/product/1485338659-... Answer Finally, refit the top case half and screw in the remaining screws. You can push the trigger after heating to get the glue. If you use a thick knife (box cutter etc), you are left with a wide gap that is not too pleasant to look at! It heats up in 45 seconds? If you regularly make crafts with fabric, lace, or ribbon, this type of glue gun is the ideal option. Whilst a latching switch sounds like a good idea, the form of heating element that's been added to this glue gun is not suited to such a switch. Remove the silicone caps on both the nozzle and the inlet sides- you want to be working with just the metal piece. Thank for taking the time to read my first instructable, I hope you learnt something or gained a few ideas of your own! APO hot melts have good fuel and acid resistance, moderate heat resistance . This results in a nice looking finished product, as the strain relief on both the cigarette lighter socket and the hot glue gun looks professionally done. Think a little piece of cellophone big enough to wrap up the paddles with that little chunk of aluminum between them. Thanks Info-Sam! The negative wire had two extensions soldered to it (and the joint covered in heatshrink). It's basically just a heating element surrounding a tube through which the glue stick is pushed, and a nozzle. If it gets about 210-220 C then you could use it to extrude PLA. When the glue has cooled (give it at least 10 minutes or you'll have to start again), the tape can be removed, leaving a nice finish that follows the case lines well. It looked shiny but I think that was thermal paste. However, the resistance of the wire does not change as the temperature increases. This looks very useful, thanks for sharing how you made it :). Instead, use an x-acto knife or a scalpel, which gives a much narrower cut. I'm not super satisfied with the way I wired up the LED, as it is only on when the button is on. Since this hot glue gun was designed to run off of the12 volt circuit of a car, a cigarette lighter plug makes perfect sense as a power connector. I'm an engineer-in-training based in Melbourne, Australia. If you’re a crafter like me, a glue gun is one of your favorite crafting tools. Hold up, what I thought was a little chunk of aluminum between the paddle contacts, I now don't think is aluminum. Cobiz Gun Kit. Looked kind of like brake pad composite material. Make sure you don't damage the kapton tape wrapped around the element as it is reused to make the 12 volt heating element. Another question. MAKE SURE THE GLUE GUN IS UNPLUGGED! It is much nicer to use hot glue when it heats up quickly! The melted and usable glue is then dispensed through a metallic nozzle, which can get significantly hot. If this is your first glue gun that you are modifying, then this can be held in pace with superglue too, just ensure the LED is a tight fit because superglue has no gap filing properties. Thus, the voltage dropped across the resistor must equal 12 - 3.4 = 8.6 volts. When the glue is squeezed out of the nozzle, it is VERY HOT, and will quickly burn skin if you are not careful. However, to make it easier I used a pre-made form of resistance: a resistor. A resistor will not produce any heat unless you apply a potential difference (voltage) across it. I love taking stuff apart to see how they work, as well as hacking stuff to make it work even better! Solving this gives us 430 ohms. If you have followed this instructable, you will now have yourself a working 12 volt powered hot glue gun! Remove all the screws- you want to be able to take the cover plates off. The positive wire (connected to the tip of the cigarette lighter socket), was then soldered to one pole of the switch. However, if the resistance is too high it will not heat up enough, and if it is too low too much power will flow, resulting in too much heat (and leading to the magic smoke being released). Yes, I know you can buy them off of Ebay and the like, but if you do there will be a couple of months wait, and they are about the same price as this one. This means a constant power flows, and so the element doesn't cool down. You can use this circuit for anything that uses a simple resistive heating element. A step drill ('Christmas tree bit') makes neat work for this. Use a little bit more glue than necessary, because if the wires touch the element it will burn through the insulation and could cause a short. We can sub this into ohms law, where r = v / i. Part of its side has been cut away so that the heating element can be seen. As this occurs, less current flows, and the element cools. The heating element liquefies the plastic glue. The gun uses a continuous-duty heating element to melt the plastic glue,. A 12 volt hot glue gun makes this useful adhesive even better- want to repair your RC plane at the field? I don't know the exact composition, but this resistance wire is good because you can actually solder to it, unlike nichrome wire. Grainger's got your back. A push-to-make switch must be used- this will send power to the heating element only when it is actually pressed. The hot glue can then be coloured black with a permanent marker to integrate it even more seamlessly into the case shape and colour. The final part is to strip the ends off the actual wires and solder them to the positive and negative contacts of the cigarette lighter plug, and then reassemble the cigarette lighter plug. A few notes: Be ready with a good amount of glue depending on how deep your molds are! On the package it said: 10 watts, AC 120-240V. Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & … Thanks seamster! It needs five to ten minutes to warm up. This is a self-governing process. Heatshrink can then be used to neaten up the connections, and again when securing the wires ensure they cannot touch the heating element. 21 hot glue gun crafts+ glue gun tips & hacks you should know. I had to remove a part of one of the screw posts at the top (as the new heating element increases the thickness of the barrel), but be careful to not cut into the threads, or the screw cannot be secured properly. It must be rated for at least the maximum current of the heating element, in this case 1.52 amps. You can fix a wobbly bench or table with your pocket change. Because resistance wire has no thermal coefficient, the resistance does not change in accordance to the temperature. Looking for MASTER APPLIANCE Heat Gun Element Kit (1A503)? Hot glue (or superglue if this is your first hot glue gun) can then be used to route the wires, ensuring they cannot touch the heating element. Be careful- it is quite thin and easily broken. The finished 12 volt heater assembly can then be tested by connecting it to a 12 volt source. Answer If it doesn't, then remove just enough plastic so that it does fit. It sounds like what little plastic that was left inside the gun overheated and charred to a solid carbon mass. The first part here is to ensure that the modified barrel fits into the original slot.
